Subject: [PATCH] Fri Aug 13 19:53:10 2004 Soeren Sandmann
 <sandmann@redhat.com> Fix for lockups on some versions of Matrox Mystique.
 #687, Patch from Mike     Harris. Call xf86EnableDisableFBAccess though the
 function pointer instead of     directly. #1041, Patch from Aaron Plattner.
 Swap the phsyical size of the screen when rotiation. #1050, Patch from    
 Aaron Plattner. Fri Aug 13 19:47:12 2004 Soeren Sandmann
 <sandmann@redhat.com> Make HAVE_FT_BITMAP_SIZE_Y_PPEM conditional on the
 FreeType version instead     of proping it. This way it will work with the
 monolithic version too.     #1062, Patch by Owen Taylor.
